For ACOs

This page contains information for Accountable Care Organizations (ACOs) applying to and participating in the Shared Savings Program, including an overview of the agreement period, as well as application resources.

Program Participation Information

For agreement periods beginning on July 1, 2019, and in subsequent years, ACOs agree to participate in the Shared Savings Program for a period of no less than five years, known as the agreement period. The agreement period is made up of performance years that follow similar operational processes.

ACOs may participate in the Shared Savings Program for agreement periods of at least five years, under one of two tracks: the BASIC track (which includes a glide path for eligible ACOs), or the ENHANCED track, which offers the highest level of risk and potential reward. ACOs participating in the BASIC track’s glide path may begin under a one-sided model and progress through incremental levels of increasing risk and potential reward.

Prepare for the next performance year by making sure contact information is current in CMS systems, maintaining their ACO Participant List and Skilled Nursing Facility (SNF) Affiliate List (if applicable), and completing the Annual Certification process; and
